> Many business incorporate in Delaware since they have very friendly business taxes.

No, that's not the reason at all. The reason is that the state judiciary has expertise in corporate law that other states don't, so litigation is smooth and predictable. You don't get a family court judge assigned to your corporate law case, as can actually happen elsewhere.

It is/was the same with East Texas and patent law, until recently at least. It became corrupted by donations of civic facilities by large litigators, so I think some companies have moved on.

> If i remember right, they also have no personal income tax

Most Delaware corporations are used by businesses in other states, so it has nothing to do with personal income tax.
